SPECIFICATION vforming part of Letters Patent No. 294,690, dated March 4, 1884.

Application filed January 8, 184. (No model.)

Zo aZZ whom it ma/ z/ concern/ Be it known that'l I, ALBERT SIoHEL, of the city, county, and State of New York, have invented anew and useful Improvement in Finjeher-Plates for use in Presses for Making Pluggobacco, of which the following is a specificaion.

My invention has reference to the platesusually lknown as finisher-plates 77-which, in the compress or nishing-press, are interposed betweenthe layers of plug-tobacco. By means of these plates the faces of the plug-tobacco are finished and made smooth at the time the tobacco is subjected to final pressure. In order to impart a proper nish to thetobacco,

.it is essential that the faces of the finisherplate should in the first instancebeas smooth as practicable, and'that they should be kept in that condition. It has been customary heretofore to make them of tinned iron-that is to say, sheet or plate iron coated with tin by the ordinary dipping process-having its tinned surfaces smoothed and polished by suitable means. Thesel surfaces, however, owing to the washing and cleaning operations to which the plates necessarily are frequently sub]- ected, soon become defective and worn, and consequently the plates fail to impart to the plugtobacco the requisite finish. It has been my object to overcome this defect and to produce a finisher-plate which shall be more durable, preserve a better nish, and which can at the same time have its faces resmoothed and polished with little trouble and expense whenever this becomes necessary. To this end I make a nisher-plate whose external faces consist of metallic tin rolled into sheet form, applied to and united with a backing ofsheet or plate iron or equivalent stiff metal, which constitutes the body of the plate. Such a plate is represented in the accompanying drawings,

inwhich- Figure l is a perspective view of the plate, and Fig. 2 is a sectional view ofthe same.

A is the backing or body of' the plate, consisting of sheet or plate iron or equivalent stiff metal, and B are the plates o f sheet metallic tin, which constitute the faces of the finisherplate. The part A is of the usual shape and dimensions of y a nisher-plate-say twelve by twelve inches. The faces B are made from metallic tin rolled in sheet form of any desired I thickness, and cut to correspond inshape and size to the faces of the plate A, to which they are to be applied. They are fitted one to each face of the backing or body A, and are mechanically united therewith by convenient means-such, for instance, as solder which ows at a lower temperature than tin-the parts, when thus put together, being consolidated and firmly united by. pressure. In this way I obtain a composite finisher-plate consisting of sheet-tin faces and an intermediate backing or body of sheet or plate iron or its equivalent.

The tin faces can be made smooth and highly polished by buing them; or, inasmuch as it is the nature of the tin to take the finish of the parts between which it is pressed, the composite plate can have a high finish and polish imparted to it b y subjecting it to pressure between a bed-plate and a plunger whose actare made of smooth and highly-polished steel. When subjected to pressure under these conditions, the tin faces of the plate take the high polish and finish of the steel, and whenever, by long-continued use or for any other reason, the tin faces of th'e platelose their polish or smoothness, they can be readily and easily renewed and brought back to their original state of polish by subjecting them again to the same operation.

united therewith', as and for the purposes hereinbefore set forth.

In testimony whereof I have hereunto set my ha-nd.

ALBERT SICHEL.
